"Lin Fei."

Ling Yao came back. Lin Fei didn't know what she was busy with all day. Every day she left early and returned late. Moreover, it seemed that her martial arts had completely fallen into disrepair. After all, she was busy every day. Where would she have time to practice martial arts?

"Senior Sister Lin, I just came back from the front line and went to the palace, I didn't have time to tell you."

"Lin Fei, I already know about your situation on the front line. How strong are you really?"

Ling Yao couldn't help but ask. When she received a report from the court's rebellion suppression army and the messages that came in successively, the whole person was a bit dazed. She was shocked. Lin Fei actually collapsed the city wall of Chiyang Prefecture with a single saber stroke.

It was not the city gate, but a wall! She also knew about Chiyang Prefecture. The city wall was high and strong. But even so, it couldn't resist Lin Fei's single saber stroke.

During the suppression of the rebellion, whatever problem or trouble the court's army encountered, it was Lin Fei who made a move, solved directly with a single saber stroke. There was almost never a second saber stroke.

For such a long time, Ling Yao only knew that her junior brother was the top genius of the Nine Profound Sect and his strength was very strong. But exactly how strong Lin Fei was, Ling Yao didn't know.

If it were anyone else asking, Lin Fei wouldn't bother. But, when Ling Yao asked, Lin Fei thought for a moment and said, "Under the Foundation Establishment, I should be invincible! Perhaps, the founder of the Nine Profound Sect in the past could barely beat me."

Lin Fei told the truth. The founder of the Nine Profound Sect, although his True Qi was perfect and his Martial Dao True Intent was perfect and he also mastered three types of Martial Dao True Intents, Lin Fei had cultivated Saber Qi and he also had Heavenly Saber Art. He could exert the power of the heavenly saber.

Even if the founder of the Nine Profound Sect came back to life, who was really stronger and who was weaker would have to be determined by a fight.

"Invincible under the Foundation Establishment..."

Ling Yao was shocked. Of course she understood what this meant. And she also knew how heavy the weight of "invincible under the Foundation Establishment" was. Not to mention that she is only a princess now, even if she inherited the title of the South King, even if she were the Great Chang Emperor, facing Lin Fei, she would have to treat him as an equal even with added respect.

She finally understood the reason Lin Fei had advised her to practice martial arts back then. Back then, Lin Fei was only a mere acquired martial artist. Even if he had become innate, actually, in terms of status, it was still slightly lower than a princess.

However, now it's completely different. Invincible under the Foundation Establishment! In the royal family, no one was an opponent except the Supreme Elder.

Such a person was a dominant force. Moreover, many immortal sects did not have a True Person in the Foundation Establishment. That is to say, they were not as good as Lin Fei. Lin Fei alone could be compared to many immortal sects!

"Senior Sister Lin, I plan to continue honing my saber intent. I hope to be able to train it to perfection. Therefore, I need to exchange ideas with some top saber practitioners. I wonder who in Chang City are the masters of saber techniques?

It's not necessarily about being strong, as long as the saber technique is outstanding, and there are one or several martial artists who have trained a saber technique to perfection, it will do."

Lin Fei planned to stay in Chang City for a while. First, "challenge" all the top saber practitioners in Chang City. Then go to meet the top saber practitioners in the world, completely solidifying his title of "Number One Saber Under Heaven", and also capturing some saber techniques to enhance the foundation of Heavenly Saber Art.

"Lin Fei, if you want to exchange ideas with the saber practitioners in Chang City, that's easy."

Ling Yao had people investigate. She soon gave Lin Fei a list. On the list, there were some masters of saber techniques in Chang City, belonging to top saber practitioners.

Of course, perfection realm saber techniques were not necessarily top saber practitioners. After all, some people could only perfect their saber technique at the Body Refining level. But those who could perfect the saber technique, especially those who could perfect the acquired saber technique, must be the top saber practitioners. They would definitely not be nameless.

The probability of "capturing" the perfection realm saber techniques was much higher.

Lin Fei looked at the masters of saber techniques in Chang City given by Ling Yao. With a sweep of his eyes, he saw the first top saber practitioner.

"Mad Saber Xiahou Zheng, who has perfected the Mad Wind Saber Technique. One of the top masters of saber techniques in Chang City. Let's start with this Xiahou Zheng tomorrow."

Lin Fei made a decision in his heart.

...

Chang City, Changping Street. Here, there was a Mad Wind Martial Arts Hall. Although it was a martial arts hall, those familiar knew that this hall was not easy to provoke.

Because the owner of the hall was "Mad Wind Saber" Xiahou Zheng, who was an innate martial artist, a generation of Masters!

Although a master opening a martial arts hall seemed a bit of a step down, in fact, the Mad Wind Martial Arts Hall did not rely on accepting disciples to make a living.

The hall only accepted disciples who were either rich or distinguished, and then relying on the Mad Wind Martial Arts Hall opened a series of businesses such as a dart bureau, restaurant, silk and satin store, and so on.

Of course, many people knew it was not that Xiahou Zheng had a business mind, but he has a few children. Relying on the Mad Wind Martial Arts Hall, they had developed to this point today.

However, no matter what, this unprofitable Mad Wind Martial Arts Hall, in fact, was the foundation of the Xiahou family.

At this moment, inside the Mad Wind Martial Arts Hall, all of Xiahou Zheng's children were present.

"Father, our Mad Wind Restaurant needs to continue expanding. We need a lot of silver. This Zhang Cheng is a famous wealthy businessman in Chang City. He just wants to pay his respects to you and use your reputation as an innate martial artist to grow his business even bigger, and he will also cooperate with our restaurant. In this way, wouldn't the problem of our Mad Wind Restaurant lacking silver be solved?"

"Yeah, that Zhang Cheng is quite sincere, you just need to accept Zhang's invitation every month and show your face..."

"Shut up!"

Xiahou Zheng's face turned pale. His gaze swept over each of his sons and daughters. Finally, he said coldly: "The martial way is the foundation. And you? All day long, all you talk about is business and silver, do you still look like martial artists?"

"Father, not everyone can become innate. If you are an acquired martial artist, what can you count in this Chang City?"

"Exactly, even if it's an innate Master, it's just a bit of face in Chang City. There are nobles and even Qi Condensation cultivators everywhere here. It's better to take advantage of your reputation as an innate Master and develop the business of our Xiahou family first. If there are any troubles, we have plenty of connections to smooth things over."

"You all..."

Xiahou Zheng was furious. He had practiced martial arts his whole life. As a result, when he came to Chang City, his children didn't practice martial arts anymore. They switched to business.

Although it seemed like they had connections and money now, Xiahou Zheng was very clear. Once he died, these connections, relationships, and money were all useless. But his sons and daughters couldn't see through it. They didn't know the true weight of an innate martial artist.

"Is 'Mad Wind Saber' Xiahou Zheng in? I, Lin, have come specially to learn from Master's Mad Wind Saber Technique!"

Just then, a cold voice came from the courtyard.

"Hm?"

Xiahou Zheng suddenly looked up and towards the entrance. At the same time, his children also stepped out. Upon seeing the visitor, his eldest son furrowed his brows slightly and said, "This is not a place where anyone can just walk in. Furthermore, my father does not accept any challenges, you'd best leave now."

However, the visitor seemed to ignore his words. He stood in the courtyard, not moving. The eldest son, a bit irked, loudly rebuked, "Who let this ruffian in? He has no manners! If you don't leave soon, I'll have the constables take you to jail. This is Chang City, how dare a martial artist like you be so presumptuous? Even if you're an innate martial artist, we can still throw you in jail!"

In Chang City, there were dedicated constables. Among them were Qi Condensation cultivators and Innate martial artists. They were specifically there to deal with troublesome Innate martial artists or Qi Condensation cultivators.

Xiahou Zheng's son, having a good relationship with some officials, had the confidence to say this.

"Whoosh".

Lin Fei's gaze landed on Xiahou Zheng's eldest son. Suddenly, Xiahou Zheng felt his body trembling. It felt like facing a treasure saber with its sharp edge exposed. A slight lack of attention, and he would be cut in half.

"Talk more, end up like this tree!"

Lin Fei flicked his finger.

"Whoosh".

A strand of saber energy instantly flew towards a big tree in the courtyard.

"Crack".

The big tree was instantly cut in half by this strand of saber energy, collapsing with a rumble.

Immediately, the faces of Xiahou Zheng's children all turned pale. Their gaze filled with fear as they looked at the young man in front of them.

"Back down!"

Xiahou Zheng came out. There was a hint of shock in his eyes.

"May I ask who you are?" Xiahou Zheng asked.

"Nine Profound Sect, Lin Fei!"

"You are the 'Immortal Slayer Saber' Lin Fei?"

Xiahou Zheng's eyes widened, and his heart suddenly shocked. He no longer counted as a member of the martial world. All these years in Chang City, he was practically a rich man.

However, Xiahou Zheng was still an innate martial artist after all. And, he was a top-level saberist. He still had some understanding of major events in the martial world.

Who was Lin Fei?

He was the notorious Immortal Slayer Saber! His saber could slay immortals!

Xiahou Zheng had heard of Lin Fei's strength. So, how could he dare to accept the challenge?

Seeing Xiahou Zheng not speaking, Lin Fei's eyes were icy, his gaze slightly disappointed.

"Whoosh".

Lin Fei, with his hand acting as a saber, made a gentle slash toward Xiahou Zheng.

"Crack".

A strand of saber energy instantly landed on the treasured saber in Xiahou Zheng's hand. Immediately, the treasured saber shattered, turning into pieces on the ground. Throughout, Xiahou Zheng didn't even draw his saber.

"'Mad Wind Saber Technique' is extremely disappointed with the original host, and actively merges into your Heavenly Saber Art."

"The progress of Heavenly Saber Art increases by 5%."

The system's voice echoed in Lin Fei's mind. This was the first time Lin Fei had encountered a martial art actively leaving its original host.

However, Lin Fei had already achieved his goal. So, he didn't seek to fight Xiahou Zheng anymore. He turned around and left directly.

However, as Lin Fei was stepping out of the Mad Wind Martial Arts Hall, he paused for a moment.

"Xiahou Zheng, your saber has become dull."

Having said that, Lin Fei took a step forward. In a few leaps, he had disappeared without a trace.
